Description

Detailed Description of the Invention

The present invention relates to an air conditioner, and more particularly, to an air conditioner in which an indoor unit and an outdoor unit are packaged in one package, which can improve the condensation efficiency.

Generally, in an air conditioner, a refrigerant gas compressed by a compressor is cooled while passing through a condenser (outdoor heat exchanger) and further becomes a low temperature, low pressure liquefied gas while passing through a capillary tube. The liquefied gas is vaporized by an evaporator (indoor heat exchanger), and at the same time, a large amount of heat is taken away to rapidly lower the indoor temperature. It can also be used as a heater that raises the indoor temperature by reversing the flow of the refrigerant. Such an air conditioner is separated into an indoor unit and an outdoor unit as described above, and is installed indoors and outdoors, respectively.

However, in order to install the air conditioner, it is necessary to install both the indoor unit and the outdoor unit, which causes a problem that the manufacturing cost increases and the installation work becomes very complicated. In order to solve such a problem, the applicant of the present application proposes “a self-cooling air conditioner that does not require an outdoor unit” (Korean patent application 1997 No. 3394), which is a package of an indoor unit and an outdoor unit. I have done it before.

Briefly explaining the self-cooling type air conditioner that does not require the outdoor unit, an evaporator, a condenser, a capillary tube, a compressor and the like are installed as components of the refrigeration cycle inside the cabinet, and the condenser is provided below the condenser. A cooling device unit for cooling the internal refrigerant is provided. The cooling unit includes an air blower for forcibly circulating air so as to pass through the condenser, and cooling water injection means for injecting cooling water into the condenser.

However, the self-cooling type air conditioner configured as described above that does not require an outdoor unit has the following problems.

First, the cooling water, which is one of the cooling means for cooling the condenser inside the cabinet, cools the refrigerant inside the condenser, while the cooling water itself has a temperature of 55.degree.
The cooling water that has risen to about 60 ° C and has been heated is circulated and then re-injected into the condenser. Therefore, if the cooling water is used for a long time, the temperature of the cooling water itself becomes high, and the refrigerant inside the condenser is properly cooled. The temperature cannot be cooled. Moreover, since the particles of the cooling water are very large, they do not penetrate into every corner of the condenser, and a sufficient condensation effect cannot be obtained.

Secondly, since the dust contained in the cooling water blocks the jet holes of the jet plate, the jet cannot be jetted or the jet force is reduced.

Thirdly, since the air, which is the other means of the cooling means, circulates in the room and the condenser, it heats up while exchanging heat with the refrigerant and is discharged into the room. That is, since the room air is used for heat exchange with the condenser, it takes a long time to cool the room to the set temperature, and the power consumption for driving the compressor becomes large.

Fourthly, since the forcedly circulated air is discharged through the exhaust port arranged at one central portion of the condenser, the circulating air gathers at the central portion of the condenser, resulting in the outer portion of the condenser. Since the heat exchange with the refrigerant flowing through the condenser is not performed and the air in the outer portion of the condenser is not discharged but remains in the condenser, the state of the refrigerant varies depending on the location of the condenser, causing a problem in the refrigeration cycle.

Therefore, an object of the present invention is to permeate the cooling means, which exchanges heat with the internal refrigerant of the condenser, to every corner of the condenser, and to maintain the temperature of the cooling means at an appropriate level at all times to improve the condensation efficiency. It is to provide an air conditioner that raises.

Another object of the present invention is to provide an air conditioner capable of preventing a supply failure or a supply failure of the cooling means.

Another object of the present invention is to provide an air conditioner that prevents an increase in indoor temperature due to circulating air that cools a condenser.

Still another object of the present invention is to provide an air conditioner in which a medium for cooling a condenser is not concentrated in a part of the condenser but is circulated uniformly.

In order to achieve such an object, the air conditioner according to the present invention comprises a machine room, a condensing room,
And a compressor, a condenser, and an evaporator respectively installed in the evaporation chamber,
And a heat exchanging means which is built in the condensing chamber and supplies the cooling water so as to change the state of the cooling water into fine water droplet particles so as to exchange heat with the refrigerant inside the condenser.

According to the air conditioner of the present invention configured as described above, the cooling water is changed into the fine water droplet particles by the heat exchange means and then is scattered into the condenser, and the water droplet particles pass through the condenser and are accumulated inside the condenser. While drawing high-temperature heat from the refrigerant, the cooling water itself changes into water vapor to condense the refrigerant, and the water vapor that has passed through the condenser is discharged to the outside of the room.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a side view showing the configuration of an air conditioner according to the present invention, FIG. 2 is an enlarged view of a heat exchange means applied to the air conditioner of the present invention, and FIG. 3 is an ultrasonic vibration plate applied to the air conditioner of the present invention. 4 is a perspective view of an ultrasonic vibration plate applied to the air conditioner according to the present invention, FIG. 5 is a perspective view of an air circulation guide plate applied to the air conditioner according to the present invention, and FIG. It is a side view showing an installed state of an air circulation guide plate according to the invention.

As shown in the figure, the air conditioner of the present invention includes a cabinet 1, a compressor 2, a condenser 3, a capillary tube (not shown), and an evaporator 4 built in the cabinet 1 for realizing a refrigeration cycle. And so on.

The inside of the cabinet 1 is divided into a machine room 1a, a condensation chamber 1b, and an evaporation chamber 1c from the lower side. A compressor 2 and the like are installed in the machine room 1a, and a condenser 3 and a condenser 3 are installed in the condensation chamber 1b. A heat exchanging means for exchanging heat with the refrigerant inside the condenser 3 is mounted.

The condenser 3 is heat-exchanged by a water cooling type and an air cooling type. That is, the cooling water changes its state into fine water droplet particles and is supplied to the condenser 3, and the external air flows into the condensing chamber 1b and is supplied to the condenser 3, so that heat exchange with the refrigerant inside the condenser 3 is performed. Be seen.

Hereinafter, the heat exchange means will be specifically described. Cooling water and external air are used as the heat exchange means. The cooling water is a cooling water storage tank 1
An ultrasonic vibrating plate 20 is installed at the bottom of the cooling water storage tank 10 to change the state of the cooling water into fine water droplet particles and scatter on the condenser 3.

An air guide tube 11 is formed in the cooling water storage tank 10 so that the water droplet particles whose state has been changed by the vibrator 21 of the ultrasonic vibration plate 20 are easily scattered to the condenser 3 side. The plate 20 is provided with a through hole 22 through which the air guide tube 11 is passed.

On the other hand, a fixed amount of cooling water is always stored in the cooling water storage tank 10, and therefore a water level sensor S is installed in the cooling water storage tank 10 and a controller (control unit) C Controls the solenoid valve V based on the water level of the cooling water detected by the water level sensor S to replenish the cooling water stored in the cooling water tank T to the cooling water storage tank 10.

A guide member 30 for guiding the discharge of air is installed above the condenser 3. The guide member 30 is formed in a conical shape whose diameter decreases toward the center as it goes upward, and an exhaust duct 40 is connected to one side of an upper end portion of the guide member 30.

On the other hand, as described above, since the condenser 3 is condensed by the cooling water and the outside air, the suction duct 50 that communicates the outside with the condensation chamber 1b is provided for supplying the outside air.

The suction port 51 of the suction duct 50 is arranged outside the room, and the discharge port 52 thereof is arranged below the cooling water storage tank 10 so that the outside air passes through the cooling water storage tank 10 and the condenser 3. ing.

A part of the exhaust duct 40 on the exhaust port side is penetrated by the intake duct 50 so that the intake and exhaust ducts 40, 50 form a double structure. With such a structure, it is possible to install two ducts 40 and 50 by forming one hole in the wall surface of the building, and thus the installation work becomes very easy.

An air blower fan 60 that forcibly circulates water droplet particles and air is attached to the center of the uppermost portion of the guide member 30, and air that guides air circulation is provided between the air blower fan 60 and the condenser 3. A circulation guide plate 70 is installed.

The air circulation guide plate 70 has a size that covers the upper portion of the condenser 3, and is provided with evenly pierced air circulation holes 71 on the entire surface of the air circulation guide plate 70.

The air circulation guide plate 70 guides the front and rear or left and right slides at its corners.
The guide holes 72 are formed in each of the guide holes 72 and are provided in the cabinet 1.
The guide hole 72 is fitted in 3 and is installed so as to be slidable back and forth or left and right through driving means such as a solenoid and a driving motor.

Reference numeral 80, which has not been described in the drawings, is a drain plate for draining the moisture adhering to the surface of the capacitor 3.

Although not shown, the cold air discharged from the evaporation chamber 1c circulates in the room to lower the room temperature, and after entering the cabinet 1, the cold air does not pass through the condensing chamber 1b, but again passes through the evaporation chamber 1c. Is flowed into.

Hereinafter, the working state of the air conditioner according to the present invention having the above-described structure will be described. The refrigerant gas compressed by passing through the compressor 2 generates high-temperature heat while passing through the condenser 3, and the generated heat is cooled by the heat exchange means and flows into the capillary tube.

Explaining the heat exchanging action of the heat exchanging means, the water stored in the ultrasonic vibration plate 20 due to the ultrasonic vibration generated by the vibrator 21 becomes fine water droplet particles and is scattered to the condenser 3 side. At the same time, the suction force of the blower fan 60 causes the air to flow from the lower side to the upper side of the ultrasonic diaphragm 10 through the air guide tube 11 to promote the scattering of water droplet particles to the condenser 3 side.

The water droplet particles exchange heat with the refrigerant inside the condenser 3 while passing through the condenser 3, that is, the high temperature heat is taken from the refrigerant, and the water droplet particles themselves change their state into water vapor.

The water level sensor S measures the water level of the cooling water stored in the cooling water storage tank 10 and sends it to the controller (control unit) C. The controller C uses the solenoid valve V to maintain the cooling water at an appropriate level based on the current level sent from the water level sensor S.
Drive (control). That is, the cooling water is changed into water droplets and is replenished with the cooling water by the amount scattered to the condenser 3. Further, the outside air is blown into the condensing chamber 1b through the suction duct 50 by the blower fan 60 and the air passing through the condenser 3 also removes high temperature heat from the refrigerant.

The water vapor and the outdoor air are circulated by the circulation force of the blower fan 60, and this circulation force acts through the air circulation hole 71 of the air circulation guide plate 70. That is, since the water vapor and the outdoor air are evenly distributed in the air circulation holes 71 of the air circulation guide plate 70, they uniformly pass through the entire area of the condenser 3.

The water vapor and the outdoor air that have passed through the condenser 3 and have undergone heat exchange pass through the air circulation holes 71 of the air circulation guide plate 70, then flow into the exhaust duct 40 along the guide 30, and then are exhausted. It passes through the duct 40 and is discharged to the outside from the discharge port 41.

On the other hand, while passing through the condenser 3, water drops adhering to the surface of the condenser 3 due to a temperature difference with the condenser 3 flow into the drain plate 80 along the inclination of the condenser 3 and are discharged.

As described above, the cooling water supplied for exchanging heat with the refrigerant flowing inside the condenser 3 is changed into very fine water droplet particles by the vibrator 21 of the ultrasonic vibration plate 20. Since it is a thing, it penetrates to every corner of the capacitor 3, and
Since the cooling water that has exchanged heat with the refrigerant of the condenser 3 is not reused but the cooling water of the proper temperature is always used, the refrigerant of the condenser 3 can be maintained at the proper temperature.

Then, the circulating force of the blower fan 60 reaches the water droplets and the outdoor air through the air circulation holes 71 of the air circulation guide plate 70, so that the water droplets and the outdoor air uniformly act on all parts of the condenser 3.

Further, since the outdoor air is sucked and used instead of the indoor air for heat exchange with the refrigerant of the condenser 3 as in the conventional case, the temperature rise in the room can be suppressed.

As described above, according to the present invention, the cooling water exchanges heat with the refrigerant of the condenser after the state of the cooling water is changed into fine water droplet particles, and since the cooling water is not reused thereafter, the internal refrigerant of the condenser is set. The effect is that the temperature can be maintained.

Since the water droplet particles are fine and the inflow of water droplets and air permeates evenly into every corner of the entire condenser, there is an effect that the condensation efficiency can be increased.

Further, there is an effect that the reliability of the air conditioner can be improved by suppressing the rise of the indoor air by the heat exchange means using the outdoor air.
